General :: SSD As Primary Or Secondary Drive On A Small Server?
Jun 6, 2010
I'm pensioning off my 10-years-old home server and replacing it with an Ubuntu 10.04 box. The two storage devices are a Western Digital Caviar Green 2.0TB HD and an Intel X25-M 34nm Gen 2 80GB SATA II 2.5inch SSD (the box has 8GB RAM and an i5 750, if it matters).
I don't care much about boot times (since I don't plan to reboot all that often;-); the main frequent, performance-demanding task will be (re)building large open source C or C++ software packages from sources (as an open source contributor, I do that often).
So, I thought I'd keep the SSD as the secondary drive and the HD as the primary one, using the SSD mostly for the files that can otherwise demand a lot of seeking (esp. in a parallel make).
However, the friendly vendor (perhaps more experienced in Windows systems than in Linux ones) thinks the "normal" way to configure the machine would be with the SSD as the primary drive. I'm pretty rusty on configuring and tuning systems, so, I thought I'd better double check on SuperUser.
I am learning software raid 1 with centos 5.5. I created the raid with out any problems and removed the first drive to check there was no problems and it booted. I have installed the old drive back in the system as hdc and need to resync the drives (used old drive as partitions correct) I thought I could use raidhotadd but id does not seem to exist anymore. how I resync the drives in the array hda primary and hdc secondary using mdadm
I have an Ubuntu 9.10 machine with three ethernet interfaces, eth0, eth1 and eth2. eth2 is connected to a private network. eth0 and eth2 are connected to two different LANs. Either one will provide access to the internet. All three networks have DHCP servers. Using Ubuntu's the default settings (And Gnome), when I boot up all the interfaces are active and my system gets three IP addresses. However any attempt to access the internet results in connection timeouts and other weirdness.
I suspect that traffic is going out on one NIC (like eth0) and coming back in on another (like eth1). I'm not sure what's going on. The only way I can access the internet at the moment is to bring two of the devices down with ifdown. How can I configure eth0 as my primary interface so all trafic goes out by default on that interface, while keeping the other two active? Also, I want to make sure Avahi broadcasts properly on all three IPs so that the computers on the LAN of eth1 can still connect to myHostname.local...
Here's my routing table: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.151.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 172.16.30.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.1.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 172.16.30.2 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 10.1.0.1 0.0.0.0 UG 0 0 0 eth1
I want the 172.16.30.2 network to be the primary one and the 10.1.0.0 network to be the secondary one. My nameservers are also incorrect. It seems like Ubuntu is bringing the networks up in order, eth0, then 1, then 2, and the DHCP information from eth1 is overriding eth0, and eth2 is overriding eth1. How can I reverse this so the DHCP information from eth0 is the "master"? This seems to be an issue with Gnome's NetworkManager.
linux newbie and i made a mistake while installing windows and linuxI made 4 primary partitions for my HD as i didnt know that only maximum 4 primary partitions are allowed.Now 25 GB of my HD is wasted. It is shown as unusable.CAN ANYONE PLEASE TELL ME IF I CAN CONVERT MY WASTED 25GB INTO SECONDARY AND USE IT WITHOUT FORMATTING AND RE PARTITIONING MY ENTIRE HD ???
My question is that simple, how can I find out what is my primary and secondary DNS? I've tried commands: $ cat /etc/resolvconf and less /etc/resolv.conf but they didn't work. Also, when I open the resolv.conf file, it only says code...
i want secondary users can able to change the files permissions of primary group?user MAC is having www as a primary and httpd as secondary group. But he want to change the file permissions (chmod) httpd group files. Is it possible or not? I think its not possible. If it`s possible then let me know how?
How do you swap between primary and secondary languages for the keyboard (using GUI not terminal codes since this is for someone else who is a beginner at computing)? I installed the secondary language in the "language" section of yast, but can't see any options for swapping on the fly. Lets say they do 99% of stuff in english, but get an email they want to respond to in the secondary language or want to write a text document using the secondary language, is there a way to switch back and forth on the fly?
Currently I am running Ubuntu 9.10 on an older P4 system with EIDE harddrives. My primary HD has a WinXP installation and GRUB. Ubuntu is installed on the secondary HD.
I am happy enough running Ubuntu that I would like to remove my WinXP disk, move the disk with Ubuntu on it to be the primary boot drive, and then install a new drive as the secondary.
However when I tried to simply move the drive with Ubuntu on it from the secondary to the primary EIDE position the system would not boot. I assume that this is because there is no boot loader currently on that drive.
how do I put GRUB on the Ubuntu drive so that it can become the boot drive? Or is there some other way to accomplish what I am after without having to reinstall Ubuntu?
I have openSUSE 11.2 KDE with NVIDIA drivers. I have a TV on the left and a monitor on the right. In the Nvidia drivers this has also been setup as stated. The TV is on position 0:0 and the monitor is in position 1920:0. The monitor has been ticked in the drivers as the primary screen.
My problem is that all application open on the secondary screen and not the primary screen (monitor) as I expect. How to the OS/drivers that will ensure that application always open on the monitor situated on the right are welcome.
im trying to open my NAT on my PS3, and it's asking for my primary DNS, secondary DNS, and default router. how will i find these on ubuntu? i got my ip and subnet mask, just need the other three.
I am working on a computer that the hard drive crashed. Inititially they had a virus, reloaded windows, and had the computer up and running. When downloading software it crashed and will not boot. I have tried all the numerous routine fixes with no success including using the repair discs. The repair discs no longer work and they are unable to get a second set. As a last resort I am able to access the hard drive when booting from Knoppix from a CD. There are a couple things I would like to try from Knoppix, but do not know if it is possible. First, Is it possible to load the boot files from knoppix? Second, can you roll back the drivers from knoppix?
Having just moved to Linux from Windows, I have never considered whether or not to partition my 250 GB external hard drive. As of right now it will only be used for data storage. Should it be partitioned? If so, what size partitions?
My Red Hat EL 5.5 64 bit edition, I've install it on my primary hard drive 12 GB it works fine and then I added secondary 20 GB hard drive (sdb1) into this system and then format it as VolGroup01 see the attachment, but how come it doesn't show up ?
I have windows xp on my first hard drive and Linux on the second hard drive.The windows hard drive is labeled hda1 and the linux hard drive is labeled hdb1.I am using GRUB to boot the linux hard drive and it is installed on hdb.Is there any way to boot the secondary linux hard drive using the windows bootloader?I have tried several online tutorials for it but none of them work.
I have a Linux application(ProMAX 5000) running in a virtual Machine on my windows OS. I am using an external Hard drive of 250G in ext2 file system as my device for large data read, write & execute file system. I have already mounted the device from /etc/fstab. But i want my application to access this device as a Primary data storage device OR Secondary storage device. What command will i invoke to partition this 250G drive as my primary or secondary storage device.
I have installed RAID 1 with mdadm and it seems to work looking att /proc/mdstat..I wanted to test the system, so I removed the power cable for one of the disks. When I startup I get this message:
Primary hard drive 0 not found...And cannot start. I'm not sure if there is something in BIOS or in the RAID config? Any ideas?
I want to install Linux Mint 11 (just came out) to a USB drive. My USB drive is 34 gb. So I want to put a 1-2 gb partition on it and install mint just to that. Is that possible? I am a noob so I want to use [URL] but the screenshots don't show an option for a partition or state any extra steps that might be involved in doing this (there's a tutorial for doing this for one of the Ubuntus using fdisk, but I don't have any linux installs right now).
I love the look of FreeNAS, but it does'nt do print server!
Must Have:
Run off a USB Flash Drive File share with Windows (I want to backup to it) Be a print server to a laser printer (USB interface) Be remotely controlled once it is setup(don't have a spare screen and it's going in a spare room/corner BUT I will need to use a GUI for setup) Free (thats why I won't use Windows) Run OK on a P3
Preferred: Power management Wireless adapter compatible
I am trying to access a mounted secondary drive through FTP, and when I try to connect to it I am not able to see any of its contents. Any suggestions? I am using Gadmin-proftp to configure. I can point it to any other folder on the main drive and see it perfectly.
I just installed ubuntu, this is my first time with it so excuse my ignorance regarding it. My issue is that ubuntu does not show my secondary slave seagate hdd .. it only shows and installs on my western digital master primary one. I need to have access to my slave drive because it has data on it which i wanna use. My secondary slave shows up in my windows and bios just fine. So what gives?
I have a secondary drive on my new RedHat Linux computer and I want to make it permanently accessible from the RedHat system that is now running on the computer.
It is an old Windows NTFS drive that was a secondary drive when this was a Windows machine.
What do I need to do to, and how do I do it: 1) Format it into a format that Linux uses. 2) After it is formatted correctly, permanently mount it so it will always be accessible 3) After it is successfully formatted and mounted, how do I access it? (For example, to add a new ascii text file to it via 'cp')
I've recently set up a fedora 13 machine to use as a media server, I've been able to get everything going except samba. I've installed a second hard drive which is mounted at /media/Core and works fine on the local filesystem. I can browse the share from my mac however when I connect I get this in the smb.log file
I am running Ubuntu Server and I recently added a new hard drive to the mix. Not replacing the old one, but adding a second one.What I want to know is how to I access that hard drive? I know in the desktop version it auto adds it, but not in the server version I checked my media folder.I installed it to be my new Samba share hard drive. So how to I get at it to use it?
I'm using rsync and crontab to do automatic backups from my /home partition on /dev/sda to my backup drive /dev/sdb3. The backup partition is ext4.
But the backup partition (sdb3) is obviously on a secondary drive, and I want to automount it when I log in. I read that you have to edit /etc/fstab to do this, but I'm not familiar with the process and can't find clear enough instructions, so I was wondering if someone could give me the command I need and maybe explain how it works?
I want to unmount the current /home from sda7 and mount it to sdb1
I had a look at system -> drives management but just was able to mount the secondary drive sdb1 as "DataDrive"
I had a look at /etc/fstab. This doesn't show the recently mounted sda7 "DataDrive"
So now I'm somewhat lost on how to achieve the goal
>> What ist the correct way to do it?
Scenario 1. Copy all contents of /home to the new drive and then switch the /home mount point
Scenario 2. Switch the mount point of /home from sda7 to sdb1 and cp the contents afterwards
>> How do I unmount /home from sda7 and mount it back to the sdb1 (ext3) when lucid doesn't use fstab (does it?) and I don't know where the drives manager stores it's information.
(Just had the idea that I need to use a live cd for not to lock the system drives (sdaN) )
For sure there is a man page or a how to somewhere i didn't just find >> A link to such information might be sufficient
